/**
* Handles POST data while AJAX request.
* It works like {Controller::handlePOST} and signaatures will be checked unless
* form is on the current page and <code>no_check</code> attribute is not specified.
*
* Typical use-case of this function is posting form with javascript with
* <code>$(form).serialize()</code> method or <code>ajaxSubmit</code> from
* jquert.form plugin.
*
* Instead of redirects, like in <code>Controller::handlePOST()</code>
* method, <code>exit()</code> calls will be used.
*
* Another difference is that no "save form values and show error boxes" sequence
* is used. If some checker of validator error are present, <code>exit()</code>
* will terminate futher form processing.
*
* Additionally, unlike <code>Controller::handlePOST</code>, handler methods could specify
* <code>responce_string</code> to return status of form processing. It will be echo'ed at once.
*
* @param null
